Hi Luke , would it be possible to get the centroid file for the OP Soundcard here ? I'm looking into doing a small run through PCBway for these also.

Thanks!

Hi Cali, I have attached it here. However, note that the Teensy 3.2 processor which this sound card uses, has been discontinued for several years, never to return. So unless you are still in possession of some from the days when it was still sold, you are likely to find it impossible to have it manufactured.

Thank you!

Yea I saw someone posted on the PJRC forums they had some available, but their asking price is a bit steep so I think I will have to find another solution.

I'd love to see this board\project updated to work on Teensy 4.0 which is currently available, or even better, to work on ESP32 which are widely available at very affordable price.

I downloaded the code from GitHub but it wasn't as easy as just "compiling" for the Teensy4.0 board, there were a lot of errors thrown that are beyond my ability to debug
